You've found the perfect pen. It's comfortable to hold, it writes smoothly and it looks great displayed on your desk or in a pen holder. What happens when the ink runs out? Use it time and again with plenty of pen refills to choose from. Whether you need to refill a gel pen, ballpoint pen, fountain pen or other type, it's easy to find a pen refill that fits.

Compatibility

The most important question to ask when choosing a pen refill is what type of pen is it designed for. Most pen refills are made to work with specific pen models and brands, so it’s important to purchase compatible refills for your particular pen(s). Some pen refills feature universal compatibility and can work with most types of pens. When it’s universally compatible, the pen refills can work with rollerball, gel or ballpoint pen refills.

Ink Color and Tip Size

Pen refills are available in a variety of ink colors to suit any preference and need, including black, blue, red and more. You should also be aware of the pen tip, which ranges in size from extra-fine to extra-bold, so you can make neat, precise lines or thick, color-saturated marks.

Specialty Inks

If you plan to use a pen for record-keeping or archiving, choose a pen refill with acid-free ink to resist fading over time. Prevent criminal check washing and other document alterations with specially formulated ink that becomes trapped in paper.
